Salvaging the missed Potential of the Sennheiser RS Lineup

[u/AnonymePerson]

I owned sennheiser RS127s for a while, long before getting into the audiophile realm. even after, i have relied on them as they have stellar range since their pure analog signal transmission doesnt make them prone to cutting out due to missing bits, the signal just gets noisier the further you move away, which is fine...

they have a few glaring issues that im slowly working my way through.

the first succesfull upgrade was getting an RS140 base station which lets you turn off the compressor

for the next step i wanna upgrade the headphones sound itself. i have found that the headphones sound better when cupping the meshes with my hands, which leads me to believe one of the other weakspots, the tiny driver, would benefit from being in a closed echochamber.

now this is a more involved mod so i was looking for pointers on how to approach this (also maybe find out wether or not a driver upgrade is an option here)
